Abstract: Under the development trend of building electrification, the energy consumption of buildings continues to increase.In order to reduce building energy consumption and promote energy conservation and emission reduction, renewable energy needs to be widely used.Distributed photovoltaic (PV) is one of the most suitable renewable energy sources for buildings. The PV system can generate electricity and consume locally on the building, and reduce the cooling and heating load of the building, thus reducing the energy consumption of the building.The photovoltaic system, power supply system and energy demand of photovoltaic buildings need overall planning and design.

1.Project overview
With the progress of energy storage technology and the reduction of cost, photovoltaic buildings with low-voltage DC power supply technology and energy storage system will become energy producers.A PV energy storage project in South Korea adopts low-voltage DC power supply. A batch of PZ72L-DE/C DC meters of our company are purchased and matched with shunt for application in this project.

2. Product introduction

PZ series intelligent DC energy meter is designed for applications such as DC panels, solar power, telecommunications base stations, and charging posts. This series of instruments can measure voltage, current, power, forward and reverse power in DC system. It can be used for local display, and connected with industrial control equipment, computers, form a measurement and control system. And it has a variety of external excuse functions for the user to choose: RS485 communication interface, Modbus-RTU protocol, relay alarm output, digital input/output.

According to different requirements, through the instrument panel keys, you can set the ratio, communication parameters.

【摘要】研究了消防疏散照明在酸再生廠房內(nèi)的設(shè)計(jì)。以某酸再生廠房為例，結(jié)合國家相關(guān)規(guī)范要求，針對酸再生廠房的結(jié)構(gòu)及設(shè)備特點(diǎn)，從疏散單元的劃分、系統(tǒng)組成、配電設(shè)計(jì)、燈具選擇及布置等方面詳細(xì)闡述了酸再生廠房消防疏散照明的設(shè)計(jì)要點(diǎn)以及注意事項(xiàng)。該設(shè)計(jì)能正確合理地布置廠房內(nèi)消防疏散照明，在緊情況下快速有效地進(jìn)行人員疏散。【關(guān)鍵詞】酸再生廠房；疏散系統(tǒng)組成；配電設(shè)計(jì)；應(yīng)急燈具選擇0.前言消防應(yīng)急照明和疏散指示
智能照明系統(tǒng)在智能建筑中應(yīng)用與產(chǎn)品選型
摘要：目前來說，科學(xué)技術(shù)迅猛發(fā)展，并很大的改變了人們的生活。隨著智能化技術(shù)的出現(xiàn)，照明控制系統(tǒng)加體現(xiàn)出智能化特點(diǎn)，可以充分利用人工和自動(dòng)化控制進(jìn)行結(jié)合，使照明系統(tǒng)能滿足人們的實(shí)際需要。與此同時(shí)，現(xiàn)代化照明系統(tǒng)不僅操作簡單，而且加便于管理，有利于好的節(jié)省人力、財(cái)力資源。本文針對智能照明系統(tǒng)的應(yīng)用現(xiàn)狀展開分析探討，并提出照明系統(tǒng)的未來發(fā)展趨勢。文章主要針對于智能照明系統(tǒng)在智能建筑中的應(yīng)用進(jìn)行簡要探討分
淺談煤礦井下智能供電監(jiān)控系統(tǒng)的設(shè)計(jì)及應(yīng)用
摘要：針對某礦業(yè)一號煤礦企業(yè)井下電力系統(tǒng)故障問題頻發(fā)的現(xiàn)狀，根據(jù)一號煤礦井下供電系統(tǒng)的實(shí)際情況，進(jìn)行了井下供電監(jiān)控系統(tǒng)的改進(jìn)設(shè)計(jì)。相較于改進(jìn)之前的供電系統(tǒng)，新供電監(jiān)控系統(tǒng)運(yùn)行穩(wěn)定，縮短了供電系統(tǒng)的故障排查時(shí)間，提高了采煤設(shè)備利用率，降低了供電系統(tǒng)維護(hù)成本，增加了企業(yè)的經(jīng)濟(jì)效益。關(guān)鍵詞：井下供電；監(jiān)控系統(tǒng)；改造設(shè)計(jì)
淺析智能消防應(yīng)急照明和疏散指示系統(tǒng)在工業(yè)建筑項(xiàng)目上的應(yīng)用
摘要：隨著我國社會(huì)經(jīng)濟(jì)的迅猛發(fā)展與城市化建設(shè)進(jìn)程的加快，大型城市綜合體建筑越來越多，隨之而來的消防管理問題不容忽視。智能消防應(yīng)急照明和疏散系統(tǒng)作為保證人員疏散的消防設(shè)施，是消防的重要組成部分。基于此，文章分析了智能消防應(yīng)急照明和疏散系統(tǒng)的組成和功能特點(diǎn)，然后結(jié)合具體工程設(shè)計(jì)，闡述了該系統(tǒng)在工程中的應(yīng)用，為智能化消防應(yīng)急系統(tǒng)的應(yīng)用及推廣提供參考。關(guān)鍵詞：消防應(yīng)急照明；疏散指示；智能消防；疏散系統(tǒng)0
